Patent EP-0317810-A3 (EP)
Title: Process and apparatus for separating cell cultures from their microcarriers
IPC: C12N5/00
Filed: 1988-11-04
Abstract: In order to obtain cell cultures in relatively large quantity, it is necessary to detach the cultures in each case from the microcarriers and transfer them to unoccupied microcarriers. To date this has been carried out intermittently by adding trypsin, which causes detachment of the cells, to a container with colonised microcarriers. A high percentage of the cells detaches rather rapidly and thus remains a long time in the trypsin solution, which has an adverse effect on these cells. 
<??>In the process, the trypsin solution is passed in a continuous flow process through the container and thus through the microcarriers. Detached cells are therefore immediately flushed out of the container, and the trypsin solution is inactivated and/or separated out after leaving the container. 
<??>The process can be used for growing cell cultures on microcarriers.

Title: Communication device
IPC: H04L12/00
Filed: 1988-12-13
Abstract: In the present invention, a transmitting-receiving 
unit (31-34) or a set of upper rank transmitting-receiving 
units and lower rank transmitting-receiving units are 
provided, and one or a plurality of circuits (41-46) selected 
by a circuit selective switch (21-24) unit from among many 
circuits are connected to the transmitting-receiving 
unit or the set. As a result, the burden of the 
control unit (11-14) provided in the communication device (1-4) is 
reduced. The maintenance of a route table which is 
used in transmitting packets from the highest rank 
station to the lowest rank station via other 
communication devices is made unnecessary by 
transferring the route table in order from the highest 
rank stations to the lowest rank stations.

Title: Photoelectric position measuring device
IPC: G01D5/38
Filed: 1988-12-24
Abstract: In the position measuring device according to Figure 1, a first grating (2) is illuminated in a so-called three-grating measuring arrangement at a specific angle ( alpha ). Two component beams (3, 4) obtained at the first grating (2) by diffraction impinge on a second grating (5) which represents the measure of the position measuring device. Renewed diffraction forms component beams (6, 6'; 7, 7') of which the two component beams (6 and 7) closest to the grating normal (0) impinge on a third grating (2') with the aid of which they are diffracted once again and caused to interfere. After the third grating (2') the component beams (8, 9 and 10, 11) whose intensity has been modulated by interference impinge on photodetectors (12, 19), which convert them into phase-shifted electrical signals and supply them to an evaluation device (not shown in more detail).

IPC: H01R43/048
Filed: 1988-05-13
Abstract: A method of pressing defectiveness detection 
adapted for the detection of the press-bonding 
defectiveness of a terminal which is attached to the 
end of a covered wire so that a wire barrel and a 
insulation barrel of the terminal are press-bonded to a 
conductor portion at the end of the covered wire and a 
covered portion of the wire, respectively, by press-­
molding. A profile (broken line) of a press-bonding load acting on 
the terminal during terminal press-bonding operation is 
detected, and the press-bonding defectiveness of the 
terminal is determined by comparing the detected press-­
bonding load profile with a reference press-bonding 
load profile (solid line). The press-bonding defectiveness of the 
terminal may be determined, as required, by comparing 
the integral value of the press-bonding load, 
calculated on the basis of the detected press-bonding 
load profile, with a predetermined reference value. 
Alternatively, the defectiveness may be determined by 
comparing a press-bonding load value at at least one 
point of time and the maximum press-bonding load value 
with predetermined reference values individually 
corresponding thereto. Preferably, the press-bonding 
defectiveness of the terminal is determined by 
separately detecting profiles of press-bonding loads 
acting on the wire barrel and the insulation barrel, 
and comparing these profiles with reference press-­
bonding load profiles individually corresponding 
thereto.

Abstract: A scanned 2- or 3-D modulated light pattern originating 
from a light source and represented by a matrix of pixels is 
projected onto a defined surface or into a defined region 
distant from the light source. A plurality of means (88) for 
modulating light one operated between at least a first mode and

a) respective modulating means (88) is in the first mode 
when its associated plurality of pixels are being scanned; 
and b) a respective plurality of pixels are not being scanned 
when its associated modulating means (88) is in the second 
mode. When a modulating means (88) is in the first mode, it 
allows light to be distributed from the defined surface or the 
defined region. When a modulating means (88) is in the second 
mode, it allows the effect produced by any light incident on the

Title: Adhesion layer for platinum based sensors
IPC: G01F1/68
Filed: 1989-12-20
Abstract: The marginal adhesion of platinum to silicon nitride is a serious issue in the fabrication of microbridge mass air flow sensors. High temperature stabilization anneals (500-1000 DEG C) are necessary to develop the properties and stability necessary for effective device operation. However, the annealing process results in a significant reduction in the already poor platinum/silicon nitride adhesion. Annealing at relatively high temperatures leads to the development of numerous structural defects and the production of non-uniform and variable sensor resistance values. The use of a thin metal oxide adhesion layer (44, 46), approximately 20 to 100 angstroms in thickness is very effective in maintaining platinum (45) adhesion to silicon nitride (42, 47), and through the high temperature anneal sequence. Moreover, incorporation of the thin metal oxide adhesion layer (44, 46) minimizes the development of structural defects, and results in significantly improved uniformity and control of platinum sensor/heater resistance characteristics.
